Patented Feb. 27, 1934 UNITED STATES EPATENr easin OVERHEAD VALVE OILER 1 Claim.

My invention relates to improvements in an over head valve oiler.

The object of my invention is to provide a lu bricant reservoir and means to position the same in working relation to the valve mechanism of an internal combustion engine or the like.

A further object of my invention is to provide a reservoir having a plurality of conduits diametrically extending therein and spaced therealong and protruding therefrom to extend thru the cover of the rocker arm system, the conduits having lubricant saturated wicks passing therethru and flexible means to seal around the conduits at the point of intersection with the cover.

A still further object of my invention is to provide an efficient valve oiling means, inexpensive, and simple to install.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of this specification, and in which like characters will apply to like parts in the different views.

Referring to the drawing:-

Fig. 1 is a fragmentary longitudinal sectional .view taken thru the invention as applied upon the cover for the rocker arms of an overhead valve engine.

Fig. 2 is a. horizontal view taken thru the cover and reservoir.

My invention herein disclosed consists of an elongated reservoir 1 as containing means for lubricant, the said reservoir being filled thru the apertured neck 2 upwardly extending and closed by an oil tight cap 3 threadedly engaging thereon. Said reservoir is spaced a short distance upward from the valve cover 4. of the rocker arm system of an internal combustion engine, the arrangement and construction of which are typical style commonly employed, the elements thereof I do not claim as a part of this invention but is illustrated to show the purpose and operation of my invention.

The cover is apertured along the top wall thereof, each aperture vertically aligned with the valve stem 5 contacting with its respective rocker arm 6, the purpose of which is to axially align conduit elements '7 extending thru their respective apertures. The said conduit elements are diametrically positioned in the reservoir, the

upper ends of which are in close proximity to the upper wall thereof, but spaced downward sufficient to permit the installation of 2. W101: 8 passlng thru the conduit. Said wick being of sufficient length to extend downward to or near the bottom of the reservoir, while the other end protrudes outward sumcient to contact with rocker arm in its upward movement, by which means lubricant by capillary attraction is applied to the end of the rocker arm adjacent the valve stem, the latter conducting the lubricant downward as oiling means for the valve and seat.

It will be understood that the said wicks may be of any suitable material having a high degree of absorption, and the abutting engagement of the wick between the upper end of the tube and the adjacent wall is means to prevent excess flow of oil from passing thru the conduit when the lubricant is splashed within the reservoir.

The portion of the wick within the reservoir extending downward to the bottom thereof as above stated is means to engage with the lubricant so long as any remains in the reservoir transmitting the same to the valve stem for the purpose specified, and being so arranged, sticking of the valves are obviated, furthermore, the superfluous lubricant is free to enter the cylinder coming in contact with the piston head saturating the accumulation of carbon which tends to remove the same more freely.

As a means of securing the reservoir to the cover, I have arranged a stud 9 spaced a short distance from each end thereof, the said stud outwardly extending and secured thereto, the outer end of the said stud is reduced and adapted to engage in apertures arranged therefor in the cover 4 and secured thereto by a nut 10 threadedly engaging with the reduced portion and being so arranged the reservoir is spaced from the said cover all substantially as shown in Fig. 1.

On each of the conduits between the cover and the reservoir is positioned a fibrous washer ll of flexible texture as sealing means to avoid sediment passing thru their respective apertures from the exterior of the cover.

The invention is subject to modifications with respect to form, proportions, and minor details in construction to render the same adaptable to different makes of motors and the right is hereby reserved to make such changes as lie within the scope of the appended claim.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

In an overhead valve oiler, in combination with an internal combination engine rocker arm cover, the cover having a plurality of apertures spaced apart and aligned longitudinally thereof, a cylindrical tank having a centrally disposed apertured neck and cap therefor thru which the tank is filled with lubricant and sealed, a plurality of thereof, the outer end of the stud reduced and threaded as attaching means to the cover and spacing for the tank therefrom, each conduit having a fiberous washer snugly engaging thereon to conceal the exposed portion of the conduit and to avoid sediment passing thru the apertures in the cover, all as and for the purpose specified.
